    Changes in Immunoreactivity of Sensory Substances within the Enteric Nervous System of the Porcine Stomach during Experimentally Induced Diabetes by Michał Bulc, Katarzyna Palus, Jarosław Całka, Łukasz Zielonka

    Published 2018-01-01
    “…Therefore, this paper analysed changes in substance P- (SP-), calcitonin gene-related peptide- (CGRP-), and leu5-enkephalin- (L-ENK-) like immunoreactivity (LI) in enteric stomach neurons caused by chemically induced diabetes in a porcine model. Using double immunofluorescent labelling, it was found that acute hyperglycaemia led to significant changes in the chemical coding of stomach enteric neurons. …”

    ENERGY EFFICIENCY AND ASSESSMENT METHODS OF TECHNOLOGICAL SYSTEMS OF WATER SUPPLY AND WATER DISPOSAL by A. A. Kapansky

    Published 2016-09-01
    “…These factors include the technical condition of the equipment and piping systems, alterations in the modes of operation of pumping units over time, a significant impact of the ambient temperature on the power consumption, amount of precipitation and the chemical composition of the effluent. As an object of management water supply and water disposal systems are considered as a totality; therefore the assessment of the energy efficiency of pipeline enterprises ought to be based on a systematic approach, whereas the existing methods are mainly based on an analysis of operating modes of individual electrical equipment, not on the whole technological system. …”

    A Method for Determination of Metals in Hybrid Metal Oxide/Metal-Carbon Nanotubes Catalysts by Joanna Bok-Badura, Agata Jakóbik-Kolon, Agata Łamacz, Krzysztof Karoń

    Published 2017-01-01
    “…Due to the fact that production processes are usually unpredictable and the total amount of metal/metal oxide deposited on the CNTs may only be estimated, the methods for examining the chemical composition are necessary. In this study, fast and simple inductively coupled plasma atomic emission spectrometry (ICP-AES) with slurry nebulization was proposed for metal content determination in hybrid CeZrO2/CNT, Ni-CeZrO2/CNT, and Ni/CNT materials. …”
